Well, its more like an order of magnitude slower than the Pi (and with a lot less RAM as well)

It's 2.4GHz, but only BLE and custom protocols (2 Mbit max, GFSK modulation). The SoC can do RFID, but you have to connect a transmitter coil to use it, which doesn't seem to be the case from the photo.

I'd guess this was just used as a remote control backup connection if LAN is not working?



That puzzled me too. I didn't remember the 52832 having WiFi, but I figured it was just faulty memory.

I think the dongle might just be Nordic's cheap evaluation board.


Maybe a 6lowpan interface for maintenance. This way he could interact with it from inside the room without having to access the closet.
